without enumerating all of the nested tags manually.

That's not possible.

One fundamental restriction of SQL is, that the number, data types and names of all columns need to be known to the database before the query starts executing. SQL can't do this "at runtime" and change structure of the query based on data that is retrieved.

You can extract the content using xmltable() - but as explained, there is no way without specifying each output column.

The issue is that you are using euclidean distance for comparing strings. Consider using Levenshtein distance, or something similar, which is designed for strings. NLTK has a function called edit distance that can do this or you can implement it on your own.

As the documentation states:

The static import statement is used to import read only live bindings which are exported by another module. Imported modules are in strict mode whether you declare them as such or not. The import statement cannot be used in embedded scripts unless such script has a type="module". Bindings imported are called live bindings because they are updated by the module that exported the binding.

There is also a function-like dynamic import(), which does not require scripts of type="module".

TL;DR :

Ok, this might be a bit of a complex ask. Essentially I am trying to make a sort of JavaScript character select screen. I have my UI all set up, and my images are all coded in HTML into the DOM.
